the yarns that are being wound into the package.

An objectyof our invention is to provide a multi le end packagehasheretofore been possible. A further object of our invention is toprovide means for imposing a uniform tension 7 on a multiplicity o yarnsthat are being led 45 to a winding device, whereby hard packages of arnsmagbe formed.

, other 0 ject of our invention is to provide means for applying atension to yarns that are being wound, which means can be 20 applied tovary the tension and which may also be used for applying a modifyingliquid to the yarns. Ot or objects of our invention will appear from thefollowing detailed descri tion. 7

e formation of multiple end packages of parallel wound yarns (i. e;yarns that are not twisted together prior to winding) has. presentedmany difliculties, since if the tensions of the individual yarns are notthe same, soft a0 packages are liable to be formed. As a re-' salt 0this limitation, it has not been commercially feasible to form largepackages of parallel wound yarn.

In accordance with our invention, we provide a device for winding amultiplicit of yarns to a windin machine under uni orm tension. This isone by causing all of the ends of the yarn to pass through exactlysimilar paths and thus be submitted to the same tension prior to beingled to the windin device.

one form of our invention, the yarns are led from their respectivebobbins or other packages arranged in a circle through balloon guidesalso arranged in a circle, and then through circularly arranged 'desbetween circular discs mounted on a spindle. A multiplicity of suchdiscs are employed and their number may be varied in accordance with the50 tension desired. The yarns then pass bearticularly to a multi licityof parallel men 0] AND. APPARATUS FOR WINDING YARN ma. mm so. was.

tween the discs and the spindle around guides to the winding devices,all under the same tension.

In order to further explain our invention, reference is had to theaccompanying drawingwherein:

igure 1 is a vertical sectional view of the special yarn rack guide andtension device and also showing diagrammatically parts of a windingdevice.

Figure 2 is a plan view ofa device and v Figure 3 is an enlargedvertical cross sec- 'tion showing the tensioning device in detail.

In accordance with our invention, we provide a rack comprising the baseortion 1 having the vertical standard 2. .he base portion lsug orts thecircumferentially arranged spin es 3 which are spaced equidistant fromthe standard 2 for holding the bobbins 4 of the yarns that are to bewound into multi le end packages. Obviously instead of bobbins, otherpackages of lyarns may be mounted on the spindle 3. T e number ofbobbins employed will vary with the number of ends required in themultiple end pack- 1.,

6. The standard 2 supports a collar 5 in which are su ported the arms 6,which have balloon gui e eyes 7 at their extremity. The to of thestandard 2 supports a concave p ate 8 having s ecial holes 9 in theouter edge thereof, which act as am guides for the individual ends. A poished steel spindle 10 is mounted on the top of the stan- -dard 2.

A plurality ofwashers 11, preferably of a soft material such as felt,are arranged aboutthe s indle 10. If desired, a modifying liqui such asaconditionin lubricating or softening liquid may be app ied to thewashers 11 for modifying the yarns passing between them as will later apear. This modif ing liquid may be applie to the felt discs, eitherintermittently or in concentrated applications, to the uppermost washer,or by 05 pro rly arranged feeds to intermediate was ers. J

The frame of the windin machine is provided with guide rods 11': or theyarn that is being passed to the winding mechanism. 6

The winding mechanism is provided with the winding s mdle l2 and thetraversing guide 13. The rawing shows a paper tube 14 for winding themultiple end cheese 15. Obvi- 5 ously packages other than cheeses, suchas irns, bobbins, cones, etc. may be wound if esired. The yarns to bewound are generally indicated as A.

The operation of the device is as follows: Bobbins or other ackages ofyarns, equal in number to that desired inthe cheese or other acka'ge tobe wound, are mounted on the spindle 3.011 the base 1 of the rack. Theyarns are threaded through the balloon guide 5 and, the orifices 9 inthe concave plate 8, then between the" same discs and are then caused topass in the space between the walls of the holes of the up er feltwashers 11 and the spindle 10. The riction due to the pas- 1 2c sage ofthe yarn between the felt washers 11 and also between the washers andthe spindle 10 causes the repaired tension. By varying the number of dscs used, the tension may be varied, as stated before. A conditioning asliquid of suitable character may be a plie to the felt washers 11, whichact as wi s for applying the same to the yarn A. The indi- V1 ual endsof yarns are then caused to pass in the form of a ribbon or band aroundthe 80 guide rods 11' to the traversing guide 13 onto the windin spindle12. When rotation is applied to t e windin spindle 14, the yarns arecaused to balloon etween the bobbins 4 and the balloon guide e es 7 andpass between the washers and a so in the space hetween the washers 11and the spindle l0, and since each individual endof yarn follows exactly similar paths the tension imposed thereon is the same for all. Asa result, hard packages such as cheeses of large size, may

e wound because of this uniform tension.-

While this invention may be applied to the winding of yarns of allkinds, such as that of natural silk, cotton, reconstituted cellulose(rayon), it is particularly suitable for winding yarns made of orcontaining cellulose acetate or other organic derivatives of cellulose.Such organic derivatives of celluloss may be other organic esters ofcellulose such as cellulose formats, cellulose pro ionate, cellulosebutyrate or cellulose et ers such as methyl cellulose, ethyl celluloseand bl cellulose. it is to be understood that the foregoing detaileddescription is merely given by way of illustration and that manyvariations may be made therein without departing from the spirit of thisinvention.
